wire.

A further object is to construct a guy wire guard which can be clampedon to the guy wire in such a manner that longitudinal movement of theguard is impossible.

A still further object is to construct a guy wire guard in which thesecuring means must be operated by a specially shaped tool so thatunauthorized persons cannot tamper with the fastening means and removethe guard.

In the drawing, Fig. 1 is a side elevation of our guard showing the sameattached to a guy wire.

Fig. 2 is an enlarged cross section taken on the line 2-2 of Fig. l withthe guy wire removed.

Fig. 3 is a fragmental section of the guard showing the clamping member.

Fig. 4 is a ragmental view of the lower section of the guard showing thewire receiving member.

Fig. 5 is a fragmental vertical longitudinal section of our guardshowing the guy wire in clamped position.

Fig. 6 is a cross section of a modified form of guard and Fig. '7 is atop plan View of one of the securing screws made use of.

In the construction of our device, we employ a guard having a lowermember 8 and an upper member 9. These members are formed of sheet metaland are substantially semicircular in cross section. One end of each ofthese members is preferably rolled in as indicated by the nu- Ymeral 10so as to leave a rounded upper end.

Placed in the member 8 is a block 1l which block is provided with acentral groove 12. This groove may be provided with spiral grooves 13 sothat when a stranded guy wire is used, the

strands will fit into these grooves and assist in holding the guard inplace. The block 11 may be provided with perforated ears 14 throughwhich rivets 16 pass. These rivets also pass through the member 8 andare for the purpose of securing the block in position.

The block 11 is also provided with outwardly extending ribs 17 whichrest on the edges of the member 8 and assist in centering the block sothat the groove 12 will always be in the same position; in other words,When a series of plan view of the upperl (Cl. .H9-31.5)

blocks as illustrated in Fig. 1 are placed in the fi.;

member 8, all of the grooves 12 will be in alignment. It will be notedthat the block 11,

A extends upward some distance beyond the upper edges of the member 8andthis projecting portion is provided with openings or recesses 18,

the purpose of which will be explained in detail later.

The member 9 has secured 'therein a block 19.

This block is provided with outwardly extending ribs 2O which serve thesame purpose as the ribs 1'7. The block 18 is provided with a pair ofextending projections 23`and with a portion 24. The portion 24 isadapted to pass over the upper surface of the block 11 while theprojections 23 abut one edge of the block 11. ly illustrated in Fig. 5.The projections 23 are provided with pins or other extensions 25 whichpass into the recesses 18 and thus prevent lateral'separation of themembers 8 and 9.

The block 19 is also provided on its two end faces with recesses 26 inwhich the inturned ends 27 of a oating lock member 28 extend. The block19, as well as the member 9 are provided with a screw threaded bore 29in which a set or securing screw 30 extends. provided with a polygonalrecess 31 for the reception of a special tool to tighten down the screw.The block 19 may also be provided with perforated ears 32 by means oiwhich the block can be riveted in position.

In Fig. 6 we have shown a modiiied form of construction in which amember 83 semi-circular in cross section is employed. This member has ablock 84 secured in position similar to the block 19. The block 34 isprovided with a pair or ears or projections which are provided with abore so as to receive a cotter key or pin 36. The block Se is providedwith a'oating lock 37 which is similar to the lock 28 and with a screw38 which is similar to the screw 30. It will be noted from Fig. 6 thatwhen the securing screw 38 is tightened, the cable 89 will have atendency to bend the cotter key 36 downwardly and thus eiectuallyprevent its removal by or dinary means.

We may also if found desirable form openings 40 in the member 8. Theseopenings are for the purpose of permitting moisture which might enterthe guard to 'pass therefrom instead of being This is clear- 1 yso Thisscrew is stopped and retained in this lower member by leaving what maybe termed a pit.

ber 9 is placed in position on the upper side of the wire in such amanner that the upper end ci the member 9 will be above the upper end ofthe member 8. When the two members are in this position, the blocks 1land 19 will be spaced apart longitudinally. The member 9 is then movedlongitudinally so that the extensions 25 will enter the recesses 18.This movement is continued until the projections 23 come in contact withone face of the blocks l1. This brings the blocks of the two sectionsinto the position illustrated in Figs, 1 and 5i. After` this, thefastening tool is introduced into the polygonal recess 31 formed in thescrew 30 and then when the screw is turned downward, the floating lock28 is forced against the guy wire 39 so that the same will be boundtightly between this lock and the lower portion of the groove 12 formedin the block 11 thus frictionally holding the guard in place.

It will be noted from Fig. 5 that the upper end of the screw 30 is sunka considerable distance below the surface of the member 9, thus This pitmay be filled with any suitable substance so as to prevent the lodgementor retention of moisture in the pit and at the same time, such fillingmaterial will prevent anyone becoming acquainted with the particulartype of opening in the screw 30 and thus prevent any tampering with theguard or loosening of the iioating lock 28.

In the modification shown in Fig. 6, the lower member 8 is dispensedwith entirely and instead the cotter key or pin 36 is used. Thisstructure has been found desirable where there is not sufficient room toplace a complete guard around the guy wire as sometimes the wall of abuilding or an adjacent guard will interfere with or prevent the use ofa second complete guard.

It will be noted from our construction that the blocks 11 and 19 areeach provided with a guy wire receiving recess and furthermore, thatsaid blocks are interlocking, that is, they interlock with each other insuch a manner that lateral movement of the blocks relative to each otheris prevented when the screw 30 is tightened.

It is also our intention when found desirable to eliminate the ears 14and 32 and spot weld the blocks 11 and 19 in place instead of riveting.
